EN BLESS-CABLE RAl LiNAY.

SPECIFICATION forming part of Letters Patent No. 301,654, dated July 8, 1884.

' Application filed July 24, 18825. (No model.)

To LZZ whom t may concern.-

Be it known that I, LEVI J. WING, of Broole. lyn, in the county ot' Kings andv Stateof New York, have invented certain new and useful Improvements in Endless-Cable Railways, of which the following is a specifica-tion.

This invention has reference to certain improvements in endless-cable railways, whereby the construction of the same is considerably simplified and rendered less expensive, so as to be adapted in a higher measure for city railways than the systems of cable railways heretofore in use; and the invention consists of a double tunnel for endless-cable railways, constructed of double yokes connected at their adjoining legs, and of top and side plates that structed of side and top plates supported by a double yoke and a' longitudinal center bar, the yoke being transversely braced and stift'-4 ened at suitable intervals by screw-rods, which also form the shafts of the rollers or idlers.

In the accompanying drawings, Figure l represents a vertical transverseseetion through the tracks of a street-rail way, showinga double tunnel arranged between the tracks, and shown in section on line as ai, Fig. 5. Figs. 2 and 3 are vertical transverse sections of the double tunnel on lines y y and e e, Fig. 5. Fig. 4 is a detail longitudinal section on line c c, Fig.

LshQWing the cable-carrying pulley in sidev elevation; and Fig. 5 'is a plan view of the tunnel with the top plate partly broken away.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents adouble'tunnel, which is placed midway between the tracks of a street-railway. The double tunnel is provided with tivo longitudinal slots, c, through which the supporting-A bars ofthe gripping attachment of the cars pass downward into the interior of the tunnel. In the double tunnel is arranged the endless cable B, which moves in opposite directions in the sections of the tunnel, it being propelled in the usual manner in cable-railways 'but of greater length laterally.

by a stationary steam-engine. The gripping attachment on the cars takes hold of the cable in the usual manner, it being applied to the side of the car instead of to the center, as heretofore. A double tunnel arranged in this manner between the tracks has the advantage that it does not break up the pavement between the tracks nor interfere with the horses, and that its surface can be slightly raised and rounded off, so as to shed the rain and snow Without interfering with the crossing of vehicles.

The tunnel A is constructed ofcast or Wrought iron supports D, of U shape, which are bolted together` at their inner adjoining legs or sides, so as to form a double yoke, D D. The outer legs of these yokes support the side plates, b b, which are bolted thereto, While the adjoining inner legs support the top plate, d, and a longitudinal bar, e, in adjoining recesses of the inner legs, as appears clearly in Figs. 1 and 2. rlhe' side Walls and bottom of the tunnelA intermediately between the double yokesare made of brick-Work covered with a layer of cement, or in any other approved manner. The top plate, d, rests upon the longitudinal bar e, and is boltedto the top parts of the inner legs of the yokes D D. It is made With both edges turned down in shape of a channel-bar, to strengthen the plate, and at the same time lap over the top parts of the inner legs of the double yokes D D, whereby these legs are firmly held together. The edges of the top plate, d, also form, with the rectangularly-bent upper edges of the side plates, b b, thelongitudinal slots for the bars of the' grippers. One yoke in every four or ve yokes supports on a common shaft secured to the inner legs of the yoke two carrying sheaves or pulleys, E, for carrying and guiding the cable B. The intermediate yokes D D are braced laterally by transverse screw-bolts f, which also lserve as shafts for the idlers or rollers F, of less diameter than the sheaves E. The idlers F serve to catch and support the cable Whenever thesame is dropped from the carryingsheaves. The sheaves or idlers carry and guide the moving cable B in opposite directions in the double tunnel A. The transverse screw-rods f f are secured rigidly to the yokes by means of screw-nuts f', applied to the outer ends of IOO the rods, and by interior jam-nuts, f 2, as shown in Fig. 2. The idlers F, which turn onthe screw-rods f, are made of Wood or any other iron, wrought-iron, wood, or other suitable material, and of any suitable cross-section, though for most purposes the construction shown in the drawings-partly of iron and partly of brick, stone, cement, &c.-is preferable for general use on the score of economy and durability.

IIa-ving thus described my invention, I claim as new and desire to secure by Letters Patentl. A double tunnel forendless-cable railways, consisting of double yolres connected at their adjoining legs, top and side plates forming longitudinal slots for the gripping attachment, interior rollers or idlers placed on transverse brace-bolts, andfcarrying sheaves or pulleys which alternate at certain intervals with the idlers or rollers, substantially as specified.

2. A double tunnel for endless-cable railways, composedof top and side plates supA ported by double yokes which are connected together and braced by transverse bolts, which also forni the shafts of the rollers or idlers, substantially as specified.

3. A double tunnel for endless-cable rail- I ways, composed of double yokes connected together, a longitudinal center bar, top and side plates attached tothe yokes, and transverse brace-rods, said top and side plates forming the longitudinal slots for the grippers, substantially as specified.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
